Republican Sen. Cory Gardner wants President Trump to work with lawmakers to narrow the scope of his steel and aluminum tariffs because he’s concerned they’ll act as a tax hike on Americans.

“I am concerned that a tariff can result in a tax on the very same people that we are trying to help in this economy, that they can actually be hurt instead of being helped by this action, so let’s work, and spend the next few weeks trying to figure out exactly how narrowly tailored the tariffs can be, and go after the bad actors,” he said on CBS’ “Face The Nation.”
